Answer:

The bacterial cells transformed with PUC18 and plasmid lux grow in the presence of ampicillin, because the DNA of bacterial cells had incorporated parts of plasmid DNA and became ampicillin resistant.

Explanation:

The bacteria showing this property is mainly known as Escherichia coli (E. coli). These bacteria cells generally shows no growth in presence of antibiotic like ampicillin. Whereas when these cells are treated with PUC 18 and plasmid lux, then the bacterial DNA undergo certain transformation due to incorporation of strands of DNA of plasmid into them. This transformation make them resistance to ampicillin, when they are cultured in agar media with ampicillin in it.

If all living things are related then where did all their differences come from?

Answer:

Hox Gene

Explanation:

First, you're question is very vital, there are many ways in classifying along with identifying all living organisms that includes; morphological analysis, molecular systematics (studying the similarities and differences of the genetic data such in the sequences of DNA, RNA, and rRNA ), homology, cladistics, etc. based on phylogenetic tree, which the study of the evolutionary among various species.

But through it said that all living organisms shared one common ancestor. However, what makes them different from one to another is the homeotic genes that called Hox Genes; which specify the fate of a particular segment or region of the body, meaning the number and arrangements of the Hox genes varies considerably among different types of animals.

For instance, Sponges have at least one homologous to Hox genes, also insects have nine or more Hox genes resulting in multiple Hox genes occur in a cluster in which the genes are close to each other along a chromosome. Therefore, increases in the number of Hox genes have been instrumental in the evolution of many animals species with greater complexity in body structure.

Overall, more Hox genes, more complexity in body structure resulting in the differences of their morphological structure.

Single depurination event occurred in the GC base pair of the sequences so find the C in the 1st sequence & find the G in the 2nd sequence. These are not repaired, so the C & G are eliminated. Then 2 rounds of replication occur in the same spots where the C & G were. Take the letter previous to the empty spots & replicate it in the empty spots. TAAT. ATTA
